Kugwiritsa ntchito
Octocrylene amagwiritsidwa ntchito ngati chophatikizira mu zodzoladzola za dzuwa ndi zodzoladzola zina.Imatha kuyamwa UVA ndi UVB (mayamwidwe osiyanasiyana 250-360nm, imatha kuletsa UVB yonse ndi gawo la UVA), womwe ndi m'badwo watsopano wamankhwala oteteza dzuwa.
1. UV absorber: Octocrylene imatha kuyamwa cheza cha UVA ndi UVB, ndipo imatha kugwiritsidwa ntchito popanga zoteteza ku dzuwa kuti ziteteze khungu ku radiation ya UV.Ikhoza kuchepetsa bwino kuwonongeka kwa kuwala kwa ultraviolet pakhungu ndikuletsa kutentha kwa dzuwa, mawanga a dzuwa ndi mavuto ena apakhungu okhudzana ndi cheza cha ultraviolet.
2. Kukhazikika kokhazikika: Octocrylene imathanso kukulitsa kukhazikika kwa zotengera zina za UV ndikuchepetsa kuwonongeka kwawo pakakhala padzuwa.Izi zimapangitsa kuti ikhale imodzi mwazinthu zomwe zimagwiritsidwa ntchito popanga zodzoladzola komanso zosamalira dzuwa.
3. Kufatsa: Poyerekeza ndi zoyamwira zina za UV, Octocrylene ndi yofatsa komanso yosayambitsa kusagwirizana ndi khungu kapena kuyabwa.Izi zimapangitsa kuti zikhale zoyenera kwa mitundu yonse ya khungu, kuphatikizapo khungu lovuta.
